Constructor & Destructor Documentation

DVInterface::DVInterface	(	const char *	config_file = NULL,
		OFBool	useLog = OFFalse
	)

constructor.

Parameters:

config_file	filename (path) of the config file to be used by the interface object. The caller should make sure that the config file really exists because the constructor cannot return an error status. If a non-existing filename (or NULL) is passed, an empty configuration file is assumed.
useLog	(optional) flag specifying whether a general log file should be used (config entry GENERAL).

Member Function Documentation

OFCondition DVInterface::addImageReferenceToPState	(	const char *	studyUID,
		const char *	seriesUID,
		const char *	instanceUID
	)

adds an image which is contained in the database to the list of referenced images of the current presentation state.

This method acquires a database lock which must be explicitly freed by the user.

Parameters:

studyUID	study instance UID of the image
seriesUID	series instance UID of the image
instanceUID	SOP instance UID of the image

Returns:

EC_Normal upon success, an error code otherwise.

OFCondition DVInterface::addToPrintHardcopyFromDB	(	const char *	studyUID,
		const char *	seriesUID,
		const char *	instanceUID
	)

adds an existing DICOM image (should be Hardcopy Grayscale) that is already present in the image database to the current print image queue without rendering it again.

The "requested image size" option is not used - the bitmap is treated as if the presentation mode was "SCALE TO FIT".

Parameters:

studyUID	study instance UID of the image, as reported by getStudyUID()
seriesUID	series instance UID of the image, as reported by getSeriesUID()
instanceUID	SOP instance UID of the image, as reported by getInstanceUID()

Returns:

EC_Normal upon success, an error code otherwise.

OFCondition DVInterface::checkIOD

(

const char *

filename

)

checks the contents of a DICOM file and displays an evaluation report on the screen.

A separate application or process is launched to handle the evaluation and display. This call returns when the check operation has successfully been launched. No information about the status or success of the process itself is being made available. This method does not acquire a database lock.

Parameters:

filename

path of file to be checked.

Returns:

EC_Normal when the process has successfully been launched, an error condition otherwise.

OFCondition DVInterface::checkIOD	(	const char *	studyUID,
		const char *	seriesUID,
		const char *	instanceUID
	)

A separate application or process is launched to handle the evaluation and display. This call returns when the check operation has successfully been launched. No information about the status or success of the process itself is being made available. This method acquires a database lock which must be explicitly freed by the user.

Parameters:

studyUID	Study Instance UID of the IOD to be checked. Must be an IOD contained in the database.
seriesUID	Series Instance UID of the IOD to be checked. Must be an IOD contained in the database.
instanceUID	SOP Instance UID of the IOD to be checked. Must be an IOD contained in the database.

Returns:

EC_Normal when the process has successfully been launched, an error condition otherwise.

void DVInterface::clearFilmSessionSettings

(

If for some reason the query/retrieve server cannot be found (i.e. because it has terminated abnormally), a TCP/IP timeout (several seconds) may occur before this method returns.

Returns:

EC_Normal if the query/retrieve process could be terminated, an error code otherwise.

OFCondition DVInterface::terminateReceiver

(

)

terminates the network receiver process (Storage Service Class SCP).

This method attempts to terminate the network receiver process by requesting a DICOM association with it and delivering a special "shutdown" command. If for some reason the network receiver cannot be found (i.e. because it has terminated abnormally), a TCP/IP timeout (several seconds) may occur before this method returns.

Returns:

EC_Normal if the receiver process could be terminated, an error code otherwise.

OFCondition DVInterface::unlockExclusive

(

)

[private]

removes an exlusive lock on the database if any.

Returns:

EC_Normal upon success, an error code otherwise.

OFCondition DVInterface::verifyAndSignStructuredReport	(	const char *	userID,
		const char *	passwd,
		DVPSVerifyAndSignMode	mode
	)

verifies and digitally signs the current structured report.

If the user ID is known (i.e. specified in the configuration file) the current structured report is verified (a verifying observer is added). If the 'mode' parameter is set accordingly and the password is correct (see verifyUserPassword) the report is also digitally signed. Please note that a document can be verified/signed more than once, but only completed documents can be verified. After signing the report no modifications should be performed before the object is stored in the database or a file. Otherwise the digital signature would be corrupted. Therefore, the SOP instance UID should be generated before calling this method. To digitally sign the report it is required that DCMTK is configured and compiled with the WITH_OPENSSL flag, otherwise only verification is available (returns an error code if mode differs from DVPSY_verify).

Parameters:

userID	symbolic user ID for given user, as returned by DVConfiguration::getUserID()
passwd	for user as entered in some GUI control
mode	flag specifying whether to verify only, verify and sign or verify and sign and finalize the document. The difference between the second and the third mode is that "finalize" always signs the entire document whereas the other mode only signs the marked items (if any, all items otherwise) and leaves out certain header attributes (e.g. the SOP instance UID and the verifying observer sequence).

Returns:

status, EC_Normal if successful, an error code otherwise.

OFBool DVInterface::verifyUserPassword	(	const char *	userID,
		const char *	passwd
	)

verifies the given password for the given user ID.

This method tries to load and decrypt the private key for the given user with the given password. If this fails, the password verification fails, otherwise the password verification succeeds. This method requires that DCMTK be configured and compiled with the WITH_OPENSSL flag, otherwise always returns false.

Parameters:

userID	symbolic user ID for given user, as returned by DVConfiguration::getUserID()
passwd	for user as entered in some GUI control

Returns:

true if password verification succeeds, false otherwise.
